To all whom it may concern:

Be it known that I, CHARLES W. KIRsoH, citizen of the United States,residing at Three Rivers, in the county of St. Joseph and State ofMichigan, have invented certain new and useful Improvements in Stair-Carpet Fasteners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to a novel construction in a device for securingstair carpets without driving nails or tacks through the said carpet,the object being to provide a simple and eflicient device of thischaracter, and consists in the features of construction and combinationsof parts hereinafter fully described and claimed.

In the accompanying drawings illustrat-V ing this invention: vFigure -1is a front elevation of a stair carpet fastener constructed inaccordance with my invention. Figs. -2- and -3-f are transverse sectionsof the same on the lines Qf-Q and 3 3 respectively of Fig. --1-. Fig.ilis a fragmentary rear elevation of the same. Fig. -5- is a fragmentarylongitudinal section of the same on the line 5-5 of Fig. -l-. Fig. -6-is a fragmentary vertical section of a stairway equipped with a carpetsecured by means of fasteners constructed in accordance with myinvention.

The objects of my invention are: First: To provide a stair carpetfastener which is adjustable in length to secure carpets of variouswidths. Second: To provide a fastener which fits very snugly in thecorner and against the carpet so as to be out of the way and present aVvery neat appearance. Third: To provide a fastener which is easilyremoved and replaced without necessitating the removal and replacementof nails or tacks whereby the carpet may be easily moved with sufcientfrequency to distribute wear thereon. Fourth: To provide a fastenerwhich is sufficiently stilf and durable to firmly hold the carpet inplace without the use of nails or tacks and which is at the same timeinexpensive and easily mounted and operated.

The fastener comprises end plates A of rectangular form equipped withintegral flanges B, C and D, the flanges C being dispo/ s/led atopposite ends of the plate A and eX- tending at an angle of forty-fivedegrees thereto, said flanges being provided with openings for thepassage of nails or screws by means of which the plate A is secured inthe corner of the step in an obvious manner, said plate being disposedat an angle of yforty-five degrees to the tread and riser when secured.The flange B is triangular and eX- tends at an incline in a directionopposite to the direction of extension of the flanges C, the free endthereof extending into the corner and the side edges thereof lying incontact with the tread and riser respectively. The flange D is disposedopposite the iiange B and is flush with the plate A, said flange D beingprovided in its middle portion with an opening E. The said end plates Aare mounted in opposed relation on opposite sides of the stair carpetand serve to secure the fastening strips. The latter consists of twostrips F and G of sheet metal each provided on its side edges withflanges H eX- tending at an angle of forty-live degrees thereto. Thestrip or member F overlaps the strip or member G and is providedadjacent the overlapping end with cleats I which are bent over so thatthe freeends thereof engage the outer faces of the lianges H of themember Gr, said cleats serving to telescopically connect or couple saidmem bers. Adjacent the free ends of the middle or web portions of thesaid members F and G are two projections J which are adapted to enterthe openings E in the flanges D of the plate A to secure said strips tothe latter. The said cleats I consist of tongues formed by cuttingU-shaped incisions in the member F in a well known manner andtheprojections J are formed by drawing up the metal to form aconcavo-convex portion as is commonly practiced.

In operation the stair carpet is laid to pass between the plates A andis pressed into the corners formed by the meeting of treads and risers.The fastening strips are then mounted inV place by laying the same uponthe carpet in the said corners and inserting the free end of the memberF underneath the flange D of one plate A so that the projection J ofsaid member enters the opening E in said flange D. The free portion ofsaid member is then firmly pressed into the corner with one hand and themember G then moved longitudinally until its free end passes under theiange D of the other plate A and the projection J and opening E engageeach other. rthe strip is thus firmly secured and prevents the staircarpet from being drawn out of the said corners.

Where stair carpets of unusual Width, stiffness or Weight of body areemployed, it becomes necessary to employ fastening means between theends of the fastening strip to prevent bellying of the latter. To thisend the member F is provided in its middle or Web portion with one ormore perforations K and the strip G is provided in its correspondingpart with a longitudinal slot L registering With said perforations andpermitting free passage of the shanks of nails or screws through themiddle portion of said fastening strip.

The device is very simple and efficient, and is obviously very easilyoperated.

I claimas my invention:

l. A stair carpet fastener comprisingfastening plates disposed onopposite sides of the carpet and secured in the corner formed by themeeting of the tread and riser, flanges on said plates extending towardthe carpet, and provided with openings, and longitudinally adjustablefastening strips provided at their ends with projections, said endsbeing adapted to pass under said flanges of said plates and saidprojections entering the openings in the latter.

2. A stair carpet fastener comprising fastening plates disposed onopposite sides ot" the carpet and secured 1n the corner formed by themeeting of the tread and riser, flanges A on said plates extendingtoward the carpet, and provided with openings, and longitudinally adjustable'fastening strips having laring side flanges and provided attheir ends with projections, said ends being adapted to pass under saidflanges of said plates and said projections entering the openings in thelatter.

3. A stair carpet fastener comprising end plates provided with flangesextending at an angle of forty-live degrees to said plate and RUDOLPHVM. Lo'rz, M. M. BOYLE.
